The usual term is Indo-European or just Aryan and it refers to all those languages (not ethnicity) sharing a common ancestry. These include the Germanic (such as English), Cel…tic, Greek and Latin (Romance) language groups..
The Aryans WERE a people with a common spoken language inhabiting the Steppes of the Caucassus from about 4500BC. The many tribes united after Zoroaster wrote his 'hymn', and they swept South into India where their written script was used as the basis for Sankskrit and the Prakrits of modern India (Gujarati, Hindi...). They created the caste system with themselves as the high cast..

Indo-Aryan is an ethno-linguistic term referring to the wide collection of peoples united as native speakers of the Indo-Aryan branch of the family of Indo-European languages.… Today, there are slightly over approximately one billion native speakers of Indo-Aryan languages, most of them native to South Asia, where they form the majority. Their cultural influence, from early on in the 1st millennium AD, reached as far east as modern Cambodia and Vietnam (Khmer and Champa kingdoms) as well as Indonesia, where it survives in Bali and in the Philippines. Modern migration gave rise to Indo-Aryan minorities on most continents.

The language of the Aryans is debated as it has not been deciphered from the texts of the Indus civilization /Harrapan civilization .Sanskrit has affinity to Greek,Latin & oth…er Indo Germanic languages with similarities in Rigveda & the Iranian Avesta.

Indo-Aryan people, live mostly in South Asia and the Indian subcontinent. This incliudes the modern day countries of India, Pakistan, Bengladesh, Sri Lanka and Nepal. I don't …know about Bhutan or Myanmar. They speak Indo-Aryan languages. Indians, speak a variety of Indo-Aryan languages and dialects; the main national language of India being the Hindi language. While other sub-ethnic groups from India speak their own such as Punjabi. Bengali people speak the Bengali language, Sri Lankans speak the Sinhala language. Nepalese people speak Nepali. Although, I don't exactly see the correlation between Germans and Indo-Aryans, because Adolf Hitler claimed he was a pure Aryan.

"Race" is such a flexible term. Some people think of there being three races (African, Asian, European) other four or five, still others as many as they need, ("Jewish race," …"Irish race," etc.) Aryans or "Indo-European" were a huge collection of peoples distinquished by speaking languages with a common parent, although that parent itself has long since mutated by the time anybody thought of the term. As it suggests, there are both European and Asian (Indian) components though not quite everybody in Europe is Indo-European, nor is everybody in India. There are even other Asian members now known only through the scripts they left, known as Tocharian Linear.
